ROLLER SIDE BEARIIF Specification of Letters Patent. Application filed November 5, 1909. florist No.

1'0 all whom it may concern:

Be it known that I, PETER N. MOORE, a citizen of the United States, and resident of Milwaukee, in the county of Milwaukee and State of Wisconsin, have invented certain new and useful Improvements in Roller Side Bearings; and I do hereby declare that the following is a full, clear, and exact description thereof.

y invention consists in what is herem particularly-set forth with reference to the accompanying drawings and pointed out in claims, its object being to provid s ur-dc, economical and eiiicient roller i. ings applicable to railway-car til'tlbis m opposition to car-bodies thereon, provision being had for travel of rollers, unde pressure, on a supporting surface in eitlrr two directions from their normal position to which they have automatic return when the pressure is removed.

Figure 1 of the drawings represents a plan view of a roller side bearing in accordance with my invention having rollers thereof part1 broken away; Fig. 2, a vertical longitiu inal section of the bearing on the plane indicated by line 2-2 in Fig. l, a link-bar in said bearing being partly broken away, and Fig. 3, a transverse section of the aforesaid bearing for the most part on the plane indicated by line 33 in Fig. 1.

Referring by numerals to the drawings, l

indicates the horizontal top, 5 and (3 upper side and end flanges, 7 and 8 side and end walls, 9 horizontal base-flanges and 10 strengthening ribs of 7 tachable to a railway-car truck by bolting through apertures 11 provided in said base flanges. A central longitudinal slot 12 is provided in the top the casting, and this slot extends through the end walls S of said casting. Lower central side recesses 13 and a transverse central base. opening in communication with said recesses are outlets for dirt, snow and water that may find their way into the casting.

Mounted on the top of the casting is a pair of anti-friction rollers 15 loose on a bolt 16 that constitutes an axle'that is of itself loose .in an upper eye of a weighthanger 17 that extends through the slot 19 into said casting. The weight preferably consists of a. pair ct rollers 18, heavier than the ones it, loose on an axle-bolt if) that is of itself loose in said hanger, and these a hollow casting at- I Wei lit-rollers are guided between the end walfs 8 of the casting aforesaid.

The side flanges 5 of the castin serve as, guards to prevent displacement o the antifriction rollers 15, in case a-nut 20 provided on the bolt 16 becomes detached, and the gravity rollers 18 are confined in said casting in case a nut 21 is lost off the bolt 19.

in practice the anti-friction rollers 15 travel, under pressure upon the top of the casting in either of two directions from their normal position herein shown by full lines, the extent of travel in one direction and the movement of parts in connection therewith being shown by dotted lines it.- Fig. 2. The end flanges 6 of the casting re curved upon their inner sides to conform. to said rollers for which they constitute stops. The travel of the anti-friction rollers 15 results in a lift of the weightin connection with the hanger 17 of its pivotal connection with said weight. When the pressure is removed from the anti-friction rollers there is descent of the aforesaid weight, whereby said rollers, the weight-hanger and the weight itself are automatically returned to normal position. )wing to the anti-friction rollers being loose on their axle, the axle loose in the weight-hanger and the hanger in pivotal connection with the weight, there is no liability of a bind of any of said'parts, nor is there any tendency of the aforesaid rollers to become flattened.

The construction and arrangement of parts herein'shown and described constitutes a preferred form of my invention, but the structure 'may be varied in matters of detail without departure from the scope of the claims herewith.

claim:

1. A roller side hearhw comprising a supporting device attachable to a railway-car truck, an anti-friction roller arranged to have travel under pressure on the supporting device in either of two directions from normal position, a weight vertically guided in said support:in device, and a weighthanger suspended Ironi the roller.

2. A roller side bearing comprising a 1101- low longitudinally slotted casting attachable to a railway-car track, an anti-friction roller mounted on the casting, a slot-engaging hanger suspended in connection with the roller, and a weight in connection with the hanger within said casting.
